in connection with the accompanying draw-' ings, is a specification;like reference characters on the drawings indicating like parts in theseveral figures. p This nvention relates to mach nes for setting laclnghooks, studs or slmllar devices and has for its generalobjects toimprove the construction, speed and accuracy of operation of suchmachines.

In operating at high speed it is desirable to engage the work firmlyovera considerablearea by the feeding means for in this way the positionof the work is accurately controlled and all danger is avoided ofdistorting the work by pulling it out of shape or otherwise. To this endan important feature of my invention consists in clamp feeding mechanismof novel construction. As herein shown a movable clamping member isprovided which takes the place of the'usual stationary work table, thismember with its cooperating clamping memher being swung transverselyabout a common. axis in feeding the work.

Another feature of the invention consists in an improved hook carryingdevice for receiving the hook from a raceway and inserting it in thework. As herein shown;

this device includes an anvil plate, the po sition of which ispositively 'but adjustably determined so that the hook may be pre sentedaccurately in line with the upsetting die. In this connection anotherfeature of the invention consists in automziticmechanism for moving theanvil plate to and from operative positionconstructed and arranged tocontrol the transverse POSllIlOII of the.

anvil plate throughout its vertical movements to and from settingposition.

Still another feature of the invention consists in novel mechanism forseparating the hooks in the raceway and'transferring them v to the anvilplate. From a mechanical standpoint it has been found advantageous so toconnect these devices that one operates the other and such constructionis herein show'nl These and a features er a6 jinv'eiaitn will be bestunderstoed and appreciated from the following descrlption' of apreferredembodiment thereof selectedhfor purposes of illustrationand shown intheaccomp'anying drawings, in which, I

timed relation.

The

lower portion of the frame vided with vertieal bearings for areciprocatory plunger 90 upon the upper end of which is mounted a hooksupporting mem ber 92. The plunger 90 has secured to it a collar 94carrying a pivoted block by which connection is made to the forward endof a cam lever 96 journaled about a transverse shaft 98 in the machineframe and havlng forks 100 formed at its rear end which embrace theoperating cam 102 on the shaft 22. The cam 102 is so set as to move thehook carrier vertically simultaneously with and in an opposite directionto the movement of the upsetting die 6. v

The plunger 90 has undercut ways at its upper end, as shown in Figs. 1and 7 which engage with an annular flange formed in a threaded nut 91.The nut 91 receives the shank of the hook supporting member 92, thevertical position of which may be adjusted by turning the nut 91 tobring the member 92 and the anvil 106 resting in the slots in saidmember into position opposite the raceway 164. .This interengagement ofthe anvil and the member 92 will insure the lateral alinement of theanvil plate and support it during the setting operation, .and ismaintained throughout the cycle of the machine. In its'upper end thehook plate supporting member 92 is recessed to receive a spring pressedclamping member 93 shaped to engage the crown of the hook and hold thehook in place during the setting operation.

A screw 95 en a in a slot in the V .i 6 member 93, lim ts its vertlcalmovement.

'An' anvil plate 106, shaped to enter the throat of the hook, issupported upon the upper end of a lever108 by an outwardly anddownwardly extending shank. This shank is received in a cut away portionof the hook supporting member 92. By means of this arrangement, the sizeof the part of the anvil which must pass through the work supportingtable is reduced and provision made for the relative displacement of theanvil and the member 92 after the hook has been set and while the partsare still within the opening in the table 46 (see Fig. 10).

The upper end of the member 92 is provided with guiding and supportinggrooves adapted to receive and support the lateral edges of the anvilplate adjacent to its active end, thus insuring the exact lateral.alinement of said plate with the die 6 and tion is effected through alink 114, see Fig. 12, which is pivotally connected to the lever 108 bya pin 113 disposed a short distance below the upper end of the lever.The link 114 has a pair of transversely extending lugs forming bearingsfor a rod 116 having a collar engaging one end of a compression spring118 the other end of which bears against one of the lugs upon the link1114. The rod 116, which in effect forms the yield ingextension ofthelink 114, is provided at its rear end with a head 120 which ispivotally connected by a pin 121 to a rocker arm 122 journaled on thetransverse shaft 124.

The upper end of the rocker arm 122 is connected through a link 126 toan oscillatory cam lever 128 which will be referred to parted to thelink 114 is sufiicient to move the stop 107 inwardly to its limit andthen compress the spring 118 so that the lever 108will be held firmlybut yieldingly in place during the upward movement of the plunger 90.While this movement takes place the link 114 will swing about the axisof the pin 121 and the spring 118 will be furtherficompressed althoughthis compres- 'sion will have no effect upon the position of the anvilplate as will be apparent.

Lacing hooks are supplied to the hook carrier from a hopper 140 whichmay be of any desired construction. As herein shown, it is provided witha picker plate 142 driven intermittently through a slotted disk 143 by apin projecting from a gear 144 journa'led upon a shaft set in the hopperbracket. The gear 144 meshes with a pinion 146 on the end of a shaft 150whicheXtends-transversely acrossthe rear of the machine and is providedwith a driving pulley 152 at its outer end. The pulley 152 is connectedthrough a belt to a small pulley 156 formed on the loose member of thedriving clutch. The lacing hooks are delivered to the race- ;way'160from the hopper 140 and pass along the raceway by gravity until theyreach the separator plate 162. This is shown in Fig. 11 from which itwill be apparent that successive lacing hooks are delivered sidewise tothe lip of the separator and are then transferred tofthe lower section164 of the raceway down which they pass with the hook opening inadvance. The separator 162 is oscillated through a link 166 con nectedat its rear end to the upper end of the cam lever 128 'before mentioned.The cam lever 128 is journaledupon the stud 20 and provided at its lowerend with forks 132 which receive a block pivotally mounted upon abracket 134 projecting upwardly from the reciprocatory slide 60. Aportion of the periphery of the separator is pro.- vided with gear teethwhich mesh with a rack formed upon the horizontal moving transferringmember 168. bored longitudinally to receive a spring pressed pin 170(see Fig. 1) which is arranged to engage the rear side of each hookreleased by the separator and push it along the raceway section 164 toset it securely upon the anvil plate 106 where the hookis held by thespring clamping member 93.

Thework in which the hooks are to be set is positioned upon the table 46shown best in Fig. '12, which constitutes also the lower member of aclamp feeding mechanism. The table 46 is supported by a downwardly andrearwardly extending shank 48 having a hub 50 through'which passes a rod36 constituting the axis about which the table 46 swings in the feedingoperation. The table 46 is bifurcated so that it may be moved close tothe setting instrumentalities. Oppositely disposed to the rear branch ofthe table is the upper. clamping member 44 which is substantiallycoextensive with said rear branch and has also a downwardly andrearwardly extending shank 40 whichacts as an edge gage for the work andis provided with a hub to receive the rod 36. The clamp member 44 isfast to the rod 36 and is moved vertically thereby as will presentlyappear. A pin 42 fast to the shank 40 of the upper clamping member andprojecting into a bore in the shank 48 of the table insures the equaland simultaneous movement of the two clamping members. The shank 48 ofthe table has an upwardly extending arm 52 terminating in a split clamp54 which holds a pin 56. To this pin is connected thefforward end of alink 58 which forms a part of the feeding mechanism. The other end ofthe link is connected to the split end 68 of a link 67 pivotally mountedupon the slide bar 60. The bar. 60 has downwardly projecting jaws 62which embrace a cam 64 on the shaft 22 timed to move the bar 60forwardly and so-swing the clamping members toward the left, as seen inFig. 12, when it is desired to feed the work. The links 58 and 67 areconnected at their common point by a pin -69 and guided in theirmovement by double radius rods 72 which extend from a sleeve 74 rigidlyconnected to the spacing lever 76. The spacing lever is pivotallymounted upon a stud 7 0 set in an arm 80 projecting from the machineframe and is urged by a spring 75 rearwardly or toward a positioncorresponding to a minimum feeding movement. This handle may be held inadjusted position by a pin 81 inserted in the plate 82 (see Fig. 2). Asthe spacing lever is swung toward the left, as seen in Fig. 12, the axisofthe radius rods72 is movedto such position The latter is that more andmore of-the motion of the slide bar 60 i transmitted to the workclampingmem'bers 44 and 46. The arrangement'of the feeding mechanism is.shown diagrammatically in my prior patent above identified to whichreference. may be had for further details of this mechanism.

Vertical movement of the upper clamping member 44 is effected throughthe rod 36 by mechanism which will now be described. The rod 36 is heldagainst angular movement and provided at its lower end with a' headcarrying a roller 34. A compression spring 38 bears upon the upper sideof the head and against a portion of the machine frame, as shown in Fig.12, tending to move the clamping member 44- downwardly and intoengagement with the work. The roller 34 is arranged to runupon the uppersurface of-a cam 32 fast upon a horizontal shaft 30 arranged to slideforwardly and rearwardly. The rod 30 is connected through a link 28 tothe lower end of an extension 26 formed upon one branch of the cam lever18. vlNhen this lever is moved forwardly at its upper end to depress theupsetting die, the'roller 34 is lifted by the cam and the clampingmember 44 disengaged from the work. On the other hand when the lever18.is moved to elevate the upsetting die at the conclusion of thesetting operation the low portion of the .cam 32 is moved beneath theroller 34 and the spring 38 permitted to lower the member 44 to engagethe work.

In order to permit the clamping member 44 to be elevated for theinsertion of the. work, its shank 40 is provided with a rearwardlyextending projection 180 arranged vto be engaged by a cam 182 fast to atransverse shaft 183. At its outer end the shaft 183 carries a forwardlyextending arm 184 to which is connectedatreadle rod 185. Depression ofthe treadle rod turns the shaft 183 and so lifts the clamping member 44temporarily against the compression of the spring 38. This movement, itwill be understood, takes place independently of the intermittentlifting of the clamping member caused by the reciprocationof the cam32..

The driving pulley 3 runs loose upon the main shaft and suitablestarting and stopping mechanism is provided for clutching andunclutching the pulley to the shaft as desired by the operator. Timingmechanism is also provided by which the machine may be stopped afterapredetermined number of complete cycles. This mechanism is not hereindescribed as it forms no part of the be briefly outlined. The spacinglever 76 crating slots in the member 92. Figs.

is moved preliminarily in accordance with thespace desired between thehooks and is held in place'by a pin 81 set in the spacing plate 82 (seeFig. 2). The upper clamping member 4 1- is then elevated to permit theinsertion of the work, the shank of this member acting as an edge gageas will appear'from Figs. 7 and 8. The machine comes to rest with a hookin place upon the anvil plate 106 so that when the machine is startedthe hook is at once forced upwardly through the 'work and its barrelclenched against the upsetting die 6 which is simultaneously forceddownwardly. During the setting operation, the active end of the anvilplate is supported by the coop- 7, 8 and 9 indicate successive stepsinthe operation of inserting and clenching a hook. At

the conclusion of the settting operation the upper clamping member A lis elevated and before the hook is disengaged by the settinginstrumentalities the two work clamping members are swung toward theright, as seen in Figs. 2 and 12, and then the upper clamping member islowered into engagement with the work. As soon as the work is engaged bythe clamping members the upsetting die 6 is elevated and the hookcarrier lowered. Figs. 3 to 6 show success1ve steps lnthe operation oithe cycle ust discussed. During this time the anvll plate 106 is swunoutwardl to disen a e the clenched book, as shown in Fig. 10, such amovement being allowed by the shape of the shank of the anvil and therelation between said anvil and the member 92. This plate is thenlowered with the hook carrier, being returned to its initial positionwhere it is received in slots in the member 92 when the hook carrierreaches its lowermost position in alinement with the raceway'section16 1. During this time the clamping members are moved toward the left,as seen in Figs. 2 and 12, and the work advances to bring the point atwhich the next hook is to be set into alinement with and between thesetting instrumentalities. The final step in the cycle consists in theoscillation of the separator plate l62 whereby a hook advanced into thepath of the transferrer 168 is pushed by the latter upon the anvil plate106.
